Safety Guide
Be sure to check the entire system for any shipping damage or parts loss. Also note damage to the shipping
cartons. Contact US Water Systems at 1-800-608-8792 to report any shipping damage within 24 hours of de-
livery. Claims made after 24 hours may not be honored.
Small parts, needed to install the system, are in a parts bags. To avoid loss of the small parts, keep them in the
parts bag until you are ready to use them.
Unpacking / Inspection
 Check and comply with your provincial / state and
local codes. You must follow these guidelines.
 Use care when handling the filter system. Do not
turn upside down, drop, drag or set on sharp protru-
sions.
 WARNING: This system does not remove biolog-
ical contaminants. US Water Systems recommends
that bacteria levels be checked periodically to en-
sure there is no bacteria present. Coliform and
E.coli most importantly.

US WATER ELECTRO-ABSORPTIVE NANOFIBER FILTER USES MECHANICAL
FILTRATION AND ELECTRO-ADHESION UTILIZING CUTTING-EDGE TECHNOLO-
GY
The US Water Interceptor Pre-Filter has a 5 micron outer filter layer (which can
be washed off if sediment accumulated). Inside the filter is another layer of pleat-
ed material manufactured of Nano Alumina Fibers that have a Zeta potential of
51 millivolts. Many contaminants are actually "magnetically" removed from the
water supply and "secured" in the Charged Filter.
US Water Interceptor Filter Specifications and Operation
 Removes Sand
 Removes Sediment
 Removes Silt
 Reduces Chromium 6
 Removes 99.9% Bacteria
 Removes 99% Cysts
 Removes Silica
 Removes Lead
The US Water Interceptor media is manufactured from a naturally occurring element called
boehmite, which has no known Health Side Effects. In fact, boehmite has long been used as
an additive to food products and digestive analgesics. Additionally, it has passed testing for
NSF/ANSI Standard 42 and 61 for potable water and USP Class VI testing and endotoxin test-
ing.

Maintenance
The Interceptor Pre-filter can be installed for up to a year. The Interceptor filter should be
changed annually or sooner depending on the water usage or water conditions.
This systems performance is dependent upon incoming water quality and factors such as iron,
sulfur, manganese, sediment and other particulates need to be addressed ahead of the US
Water Interceptor Pre-Filter. Life expectancy of the filter varies with the water supply, but many
users experience filter change intervals in excess of a year when coupled with proper pre-
treatment
Where to Install
The Interceptor Pre-filter should be installed as one of the last pieces of equipment in the line
of treatment in the US Water system. Water feeds with iron and other precipitants may cause
premature failure. If there are known extreme contaminant levels, those contaminants should
be removed first. For installation questions please call 1-800-698-8792.
WARNING! The US Water filtration system should not be installed in direct sunlight.
The heat and UV light may cause the material to disfigure. Due to the transparency of the filter
housing, photosynthesis may occur and cause algae to form on the outside of the filter and on
the inner filter housing wall. Make sure the system is sheltered from the sun.
WARNING: If extreme contaminant levels are present in the feed water, iron removal
and sediment control should be installed prior to the US Water Interceptor.
US Water Interceptor Filter Installation Instructions

US Water Filter Installation Instructions
1. Install the Interceptor system in the desired location in the water treatment system. Typically
this will be the first component in the line of treatment. The cap is marked “IN” and “OUT”
on the top of the housing.
2. Mount the housing to the bracket using the supplied screws, orienting the housing to match
the applications’ desired flow direction.

3. Install threaded nipples or other threaded fittings in the housing. Be sure to use Teflon tape
on the fittings. Tighten them with channels locks. If flex pipes with rubber gaskets are used
there is no need to Teflon tape the outer fittings. If a normal plumbing fitting is used then
be sure to Teflon tape the outer fitting.
4. Mount the filter to the wall using the necessary fasteners for the wall type. Mark the hole
locations on the wall using a marker or pencil while holding the filter housing level. If this is
to be mounted to a studded wall, a mounting board can be used. A shelf board or plywood
can be mounted to the studs, then the filter housing can be screwed to the plywood or shelf
board. (Shelf board pictured below).

5. Shut off the water and release the water pressure at the lowest sink or spigot. Cut the pipe
and connect it to the filter. Connect the inlet plumbing to the inlet on the filter housing .
Tighten with channel locks.
6. Connect the outlet plumbing to the outlet on the filter housing. Tighten with channel locks.
NOTE: The connections above are made using the installation kits used with the US
Water Systems Modular Filtration System. These flex pipes have a rubber gasket and
do not require Teflon tape. If pipe fittings are used be sure to use Teflon tape on the
threads prior to installing the fitting on the filter housing. If copper pipe and fittings are
being used make sure all solder joints within 12-15” of the filter housing are completed
and the pipe is cool, prior to connecting it to the housing fittings.

US Water Filter Installation Instructions
1. Remove the sump from the filter housing and install the filter. A very small amount of sili-
cone grease or water can be used to lubricate the O-rings on the filter. The filter housing
cap has a coupling that will accept the o-ringed nipple on top of the filter. Install the filter so
the nipple on the top is fully seated in the filter housing cap.
2. Lubricate the O-ring on the filter housing sump and install it. Tighten the filter sump hand
tight. That should be adequate. Do not use abrasive tools to tighten the housing or dam-
age may occur.

10
US Water Filter Startup Instructions
1. Open a faucet or spigot down stream of the filter. Slowly open the water shutoff valve and
let the filter fill Air will be pushed out of the filter through the open spigot or faucet down-
stream. Once there is no air coming out of the faucet or spigot, turn the water supply on
fully and shut the faucet or spigot.
2. Check for leaks. If there are no leaks the filter is installed and ready for service.

11
US Water Filter Cartridge Replacement Instructions
1. Shutoff the water supply.
2. Open a faucet of spigot closest to the filter housing and allow all the water to empty from
the plumbing system.
WARNING! If the pressure is not released, the filter sump will be very difficult to get
loose. It is imperative that the water pressure is released prior to attempting to remove
the filter sump.
3. Remove the sump by spinning it counterclockwise until the sump is completely removed.

6. Remove the old filter and discard.
7. Lubricate the O-rings and install the new filter in the filter housing cap.
8. Lubricate the o-ring for the sump and lubricate the sump threads with food grade silicone
grease.

US Water Filter Cartridge Replacement Instructions
9. Install the filter sump in the filter cap by turning it clockwise until it is hand tight.
NOTE: The housing should spin tight fairly easily. If not, add more lubrication to the
sump threads. This will aid with removing the sump when the filter needs to be replaced
again.
10. Turn on the water supply and open a spigot downstream of the filter to release the air.
11.Once the air has been released, fully open the supply valve and close the faucet or spigot.
12.Check the housing for leaks and repair as necessary.
